The lesson question for this lab is “What is the effect of the type of food available on the frequency of different types of bird beaks?” The the lab procedure you just studied should help you address this question. Will it? Explain. Why is the percentage of food eaten a good number to use? Explain.

All individuals have two alleles for a given trait. according to mendel's these alleles are passed down one each from both mother and father.

If a strand of dna has 35% thymine. what is the percentage of cytosine, adenine, guanine?

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. an incomplete dominance cross is performed between a bird that is homozygous for red feathers and a bird that is homozygous for blue feathers. purple offspring result. then, two of the purple offspring are crossed. according to the punnett square for this cross, how many of the offspring from the second cross will have a feather color that results from incomplete dominance? 1 in 4 2 in 4 3 in 4 4 in 4
